Down converting HD to SD
Importing HVX200 960×720 (1280×720) and when I go to select 720×480 or 486, the image is stretched?
1280×720 – 1.7777777
720×480 – 1.5
720×486 – 1.4814814
720×405 – 1.777777
There probably is an easy explanation to all of this, but any insight would be grateful.
Here is an example image file of both cases.
Thank you!

DVCPRO HD at 720p…as you noted…is 960×720. Anamorphic…not full raster 1280×720. It is squeezed into the 4:3…960×720 frame. FCP unsqueezes it, as it detects the anamorphic flags. As does Quicktime. But convert it to another 4:3 option, like 720×480 or 720×486…it will be squeezed.

Thanks for the info Shane, what do you suggest is the best way to export the file out of FCP while down converting it to NTSC for the station?

They want a file? In what format? And do they want it 4:3 cropped? Meaning the sides chopped off…Pan and Scan. Or will they accept letterboxed?

We haven’t gotten that far yet. I’m doing this edit for another production company and once they approve the spots, then we will find out how it’s being delivered.
It’s such a pain all of these different formats and aspect ratios. I wish there was an easier solution for all of this.

Finding out the specs BEFORE you edit, or online, is really important. Because you might shoot and edit planning for the 16:9 frame, and the network will go “we want a 4:3 cropped final.” And this means you will lose the sides, and might mess up the framing you had, and you will have to literally pan and scan each shot.
But that’s advice for the future. Don’t worry about what you need to do for final delivery until you get those specs. THEN try to figure out what needs to be done.

Understood, however, I did not shoot this. Once I find out what the final specs will be, I will let you know.
But, I still don’t understand how the footage is looking the way that it does in FCP. Is it because it’s taking the 960×720 and converting to 720×480 (16:9).
Sequence file –
Frame Size – 960×720
Vid Rate – 23.98
DVCPRO HD 720p60
HD Pixel Aspect – (960×720)Quicktime Conversion –
NTSC 720×480 16:9 or NTSC 720×486 16:9
both do not look right. What is wrong here?

[Josh Woll] “NTSC 720×480 16:9 or NTSC 720×486 16:9”
Neither of those are 16:9. Those are 4:3 formats. There is no SD 16:9 format. Doesn’t exist, except in PAL (Europe)…720×576. The US didn’t do NTSC 16:9. So you either deliver a 4:3 cropped, or letterboxed final.

Export using “Current Settings”
Drop that into compressor to create your delivery.This assumes you know the end target ahead of time.
